Ok, so I added the spin on filter set for my duece and installed it today. When I went to get the 6 micron filter they only had one so I decided to get one six micron and one 12 micron filter. I am curious which filter the oil goes thru first. Is it the one closer to the cab or the front of the truck? Just this way I can put the 12 micron one on first so it can do its job then on to the 6 micron to further filter it.
